Nwere ike ịgbazehydroxypropyl methyl cellulose (HPMC)bụ ụdị cellulose ether na-abụghị ionic, nke e ji polymer cellulose mee site na usoro nhazi kemịkalụ. Hypromellose (HPMC) bụ ntụ ọcha nke na-agbaze na mmiri oyi iji mepụta ihe ngwọta doro anya, viscous. O nwere ihe ndị dị ka thickening, adhesion, dispersion, emulsification, film formation, suspension, adsorption, gelation, surface activity, water restoration and colloid protection. Mmiri bụ ihe dị mkpa nke hypromellose HPMC, nke ọtụtụ ndị na-emepụta moto ngwakọta mmiri na China na-echegbukwa. Ihe ndị na-emetụta mmiri idobe moto ngwakọta mmiri gụnyere ọnụọgụ HPMC, viscosity nke HPMC, nha ihe na okpomọkụ nke gburugburu ebe obibi. Hypromellose HPMC na-arụ ọrụ dị mkpa na moto n'akụkụ atọ: ezigbo idobe mmiri ya, mmetụta ya na nguzosi ike moto na thixotropy, na mmekọrịta ya na simenti. Ọrụ idobe mmiri nke cellulose ether dabere na mmiri nke ntọala ahụ, ihe mejupụtara moto, ọkpụrụkpụ moto, mkpa mmiri nke moto na oge ntọala nke ihe ntọala. Ka hypromellose na-apụta ìhè nke ọma, otú ahụ ka njide mmiri ka mma.
Ihe ndị na-emetụta njide mmiri nke ihe e ji amịpụta mmiri gụnyere viscosity nke cellulose ether, ọnụọgụ mgbakwunye, ịdị mma nke ihe ndị ahụ na okpomọkụ ọrụ. Ka viscosity nke cellulose ether na-amụba, otú ahụ ka njide mmiri ka mma. Viscosity bụ paramita dị mkpa nke arụmọrụ HPMC. Maka otu ngwaahịa ahụ, nke a tụrụ site na ụzọ dị iche iche nke nsonaazụ viscosity dị iche iche nke ukwuu, ụfọdụ ọbụna okpukpu abụọ nke ọdịiche ahụ.

Agbanyeghị, ka viscosity dị elu, otú ahụ ka ibu molekul nke HPMC dị elu, otú ahụ ka ọ ga-esi gbazeeHPMCga-ebelata dịka o kwesịrị, nke nwere mmetụta ọjọọ na ike na arụmọrụ owuwu nke ngwa agha. Ka viscosity dị elu, otú ahụ ka mmetụta siri ike nke ngwa agha ka mma, mana ọ bụghị nke kwekọrọ na mmekọrịta ahụ. Ka viscosity dị elu, otú ahụ ka ngwa agha mmiri ga-adị, ma maka owuwu, arụmọrụ nke scraper na-arapara na nnukwu njikọta na ihe mkpuchi ahụ. Mana ọ baghị uru ịbawanye ike nhazi nke ngwa agha mmiri n'onwe ya. Ma owuwu, arụmọrụ maka arụmọrụ mgbochi iwụda. N'ụzọ dị iche, ụfọdụ hypromellose agbanwere agbanwe nwere viscosity dị ala ruo nke ọkara egosila arụmọrụ dị mma n'imeziwanye ike nhazi nke ngwa agha mmiri. Ka ọdịnaya nke cellulose ether dị elu na ngwa agha, ka ihe onwunwe ijide mmiri ka mma, ka viscosity dị elu ma ka mma ihe onwunwe ijide mmiri. Ịdị mma bụkwa ihe ngosi arụmọrụ dị mkpa maka hypromellose. Ịdị mma nke hypromellose nwekwara mmetụta ụfọdụ na ikike ijide mmiri ya. N'ozuzu, maka hypromellose nwere otu viscosity mana dị iche, n'okpuru otu ego mgbakwunye ahụ, ka mma viscosity ahụ ka mma, ka mmetụta njide mmiri ka mma.
N'ime ite mmiri a gwakọtara agwakọta, mgbakwunye nke cellulose ether HPMC dị obere nke ukwuu, mana ọ nwere ike ime ka arụmọrụ owuwu nke ite mmiri a gwakọtara agwakọta dịkwuo mma.
